All to many don't understand that the church did not begin in the new testament. Thus we have these statements about something which is not true.
The church began with prophets like Enoch and Elijah, Moses and Noah. How is it that this is so you ask. Ask yourself what constitutes the church. The church is founded on faith which is the gospel message. Abraham believed God and it was accounted to him for righteousness. Too many fail to realize that those who come with Christ were already dead as attested to those who reign with Him for the thousand years who come out of the tribulation and did not bow to Satan, thus they are killed for Gods sake. Stop trying to add things to the scripture like those who come with Him were Raptured. Not so. If you don't believe what I have said go look at the book of Revelation chapter 6 verses 9 through 11. There are already saints in heaven even as I write this so why believe this false teaching. It is one of the reasons there will come a falling away when it doesn't happen as so many believe. The elect are the church through all ages because God has chosen them from the foundation of the world just as he did Christ according to their faith.
One last note to put the nail in the coffin is this verse from Matt:
The elect is still here in the tribulation whether you believe it or not. It is in the word spoken by Christ himself.

You are wholly neglecting two facts. First, the church was still in the future when Jesus said "on this rock I will build My church."
Matthew 16:18
And Israel, not the church, is clearly called God's "elect" in several scriptures.
4 For Jacob My servant's sake, And Israel My elect, I have even called you by your name; I have named you, though you have not known Me.
Isaiah 45:4
8 Thus says the LORD: "As the new wine is found in the cluster, And
one says, 'Do not destroy it, For a blessing
is in it,' So will I do for My servants' sake, That I may not destroy them all.
9 I will bring forth descendants from Jacob, And from Judah an heir of My mountains; My elect shall inherit it, And My servants shall dwell there.
10 Sharon shall be a fold of flocks, And the Valley of Achor a place for herds to lie down, For My people who have sought Me.
11 "But you
are those who forsake the LORD, Who forget My holy mountain, Who prepare a table for Gad, And who furnish a drink offering for Meni.
12 Therefore I will number you for the sword, And you shall all bow down to the slaughter; Because, when I called, you did not answer; When I spoke, you did not hear, But did evil before My eyes, And chose
that in which I do not delight."
13 Therefore thus says the Lord GOD: "Behold, My servants shall eat, But you shall be hungry; Behold, My servants shall drink, But you shall be thirsty; Behold, My servants shall rejoice, But you shall be ashamed;
14 Behold, My servants shall sing for joy of heart, But you shall cry for sorrow of heart, And wail for grief of spirit.
15 You shall leave your name as a curse to My chosen; For the Lord GOD will slay you, And call His servants by another name;
16 So that he who blesses himself in the earth Shall bless himself in the God of truth; And he who swears in the earth Shall swear by the God of truth; Because the former troubles are forgotten, And because they are hidden from My eyes.
17 "For behold, I create new heavens and a new earth; And the former shall not be remembered or come to mind.
18 But be glad and rejoice forever in what I create; For behold, I create Jerusalem
as a rejoicing, And her people a joy.
19 I will rejoice in Jerusalem, And joy in My people; The voice of weeping shall no longer be heard in her, Nor the voice of crying.
20 "No more shall an infant from there
live but a few days, Nor an old man who has not fulfilled his days; For the child shall die one hundred years old, But the sinner
being one hundred years old shall be accursed.
21 They shall build houses and inhabit
them; They shall plant vineyards and eat their fruit.
22 They shall not build and another inhabit; They shall not plant and another eat; For as the days of a tree,
so shall be the days of My people, And My elect shall long enjoy the work of their hands.
Isaiah 65:8-22
